This extension uses the Prometheus Elasticsearch Exporter to collect metrics.

First, you'll need to install the Elasticsearch exporter on every host you want to collect metrics for. This can be done by using the prebuild binary or a docker container as seen on the exporter's github page. To get all the metrics this extension can offer, you need to enable the following options on the exporter:

• --es.all
• --es.cluster_settings
• --es.indices
• --es.indices_settings
• --es.indices_mappings
• --es.shards
• --es.snapshots

In Dynatrace, download the Elasticsearch extension and click Add monitoring configuration next to an extension version under the Versions list. Select the host you want to monitor then define the URL to the /metrics endpoint on your Prometheus instance or Elasticsearch exporter on your host. Finally, select the feature sets containing the metrics you want to import.
